<p>A compressor housing (20) comprises a housing body (21) which encompasses an impeller (12), an introduction section (30) which introduces air toward the impeller (12), and a port section (40) which is provided next to the introduction section (30). A valve body (51) which opens and closes a bypass path (2b) bypassing the impeller (12) can be seated on the port section (40). A connection hole (34) to which a recirculation path (6) is connected is formed in the side wall (31) of the introduction section (30), the recirculation path (6) allowing the blow-by gas of an internal combustion engine to be recirculated therethrough. The introduction section (30) and the port section (40) has a common wall (33) which is a side wall shared by both the introduction section (30) and the port section (40), and a communication hole (36) which forms a part of the bypass path (2b) is formed in the common wall (33). The communication hole (36) is formed so that, when the communication hole (36) is projected along the center axis (C) thereof on the side wall (31) in which the connection hole (34) is formed, the projection is included within the connection hole (34).</p> |
